About me & Submission details
� Parveen Yadav
� Security Researcher aka Ethical Hacker .
� Working as a Freelancer .
� White Hat Hacking work.
� Few Recognitions :-
� Got listed my name in Google Hall of fame,Amazon,Paypal,Adobe
& Few others.
� Paper Title :- Cloud Computing & Security .
Cloud Computing
What is Cloud Computing ?
� Cloud Computing is a technology used to provide:
� Ease of access to user data, programs and security
� Services anytime and anywhere� Services anytime and anywhere
� Ensuring complete reliability and security
� Reduces the cost of work..least possible expenditure
BASIC Characteristics of Cloud Computing
� Multi-tenancy� Resources in cloud systems can be
shared among a large number of users.
� Improve the efficiency of cloud systems
and save cost for cloud service
providers.
..
� Scalability
� Even when the total work load for a cloud
system increases dramatically, the system
could improve its capacity by adding more
hardware to handle the increased load hardware to handle the increased load
effectively
..
� Elasticity
� A cloud system only delivers the minimum
amount of computing resources that meet
users’ need. The amount of resources provided
to users increase when they need more, and to users increase when they need more, and
decrease when they need less. Users only pay
for whatever they consumed.
..
� Device Independent
� Users can utilize cloud services using
whatever device they have, should it be a
laptop, an iPad or a smartphone, as long as
they have access to the Internet.they have access to the Internet.
..
�Low-cost
� Computing resources are provided by cloud systems.
Users do not need to purchase expensive computers
to perform tasks that need high performanceto perform tasks that need high performance
computing.
..
� Reliability
� Multiple redundant sites are used in cloud systems.
There are always backups available when one or
more sites are down.more sites are down.
History of cloud computing
Evolution� The idea of cloud computing dates as far back as the 1960’s
when John McCarthy envisioned a time when computation
may someday be orgainsed as a public organisation.
� Cloud computing has evolved through a number of phases
which include grid and utility computing ,application service
processing(ASP),software as a service (Saas)
� Grid Computing a form of distributed computing,acting in concert to perform very large
tasks.
� Utility Computing a metered service similar to a traditional public utility such as electricity.
Cloud Computing is an Evolution in IT

Major services
Major Services
� Few other types of Clouds�Network as a Service (NaaS)
�Storage as a Service (STaaS)
�Security as a Service (SECaaS)
�Data as a Service (DaaS)
�API as a Service (APIaaS)
Cloud Service Models
� Software as a Service (SaaS)
� Service provider’s apps
� User’s do not manage the Network, Servers, OS, Storage or applications by the user
� Platform as a Service (PaaS)
� User deploys their apps on the cloud� User deploys their apps on the cloud
� Controls their apps
� User’s do not manage Servers, IS, Storage
� Infrastructure as a Service (IaaS)
� User’s get access to the infrastructure to deploy their content
� Doesn’t manage or control the infrastructure
� Does manage or control the OS, storage, apps, selected network components.
Cloud Deployment models
� Public Cloud computing environment are open for
use to anyone who wants to sign up and use them.
� These are run by vendors and applications from
different customers are likely to be mixed together on different customers are likely to be mixed together on
the cloud’s servers, storage systems, and networks.
� Examples of a public cloud: Amazon Web Services and Google's AppEngine .
� A private cloud is basically an organization that
needs more control over their data than they can get
by using a vendor hosted service.
� A hybrid cloud combine both public and private
cloud modelscloud models.
Google Docs
�A cloud based online Office
�Allow you to create, edit and share documents online using web browsers, iPads or even smart phones.even smart phones.
